Ever since iCloud Calendar became publicly available I am using it to arrange my schedule. I meet with people from other countries on a regular basis and I'd like the calendar reminder emails I send to people when setting up a meeting to be in english. Unfortunately, that's not the case. iCloud always sends my meeting invites in my native language (the country my AppleID is assigned to).

It seems that iCloud is ignoring my OS and iCloud Web interface language choice, as they're both set to english.

Is there a way to set the language of calendar reminder emails somewhere?
